IM PROVEO TOILET SOAP.l

Specification forming part of Letters Patent No. 56,068, dated July3,1866.

To 'all 'whxom it may concern:

Be it known thatI, GEORGE H. LlNcOLN, of the city and county ofProvidence, in the State of Rhode Island, have invented a new and usefulImprovement in Toilet Soaps; consisting of .a soap-which, in itscomposition, incorporates an ineffaceabletrade-mark, whether suchtrade-mark is an arrangement of letters or an. ornamental design; and Ido hereby declare that the following specification, taken in connectionwith the drawings making a part of the same, is a full, clear, and exactdescrip- Figure l is a view of a cake of soap made with' my improvement.Figs. 2 and 3 illus- My invention consists in arranging soaps ofdifferent colors in the same cake or bar, so as through such cake orbar, so that a cross-section will always show such trade-mark or design.

Its value as a means for securing an ineffaceable trade-mark ordistinctive ornamental figure is apparent. v

'In the accompanying drawings, A, Fig. 1,

tion of a bar or may be molded by itself sepa- B represents anornamental design, which the color 'of the body of the cake.- Thearticle is thus produced.

C represents a mold, of tin or of any other suitable materi-al, and inthis instance is a length, corresponding to the length of the bar ofsoap to bemade. n

D is a second mold, similar to the first, but made `in the form of theintended design.

The mold C is placed upright upon one end and the mold D placed withinit. color is then, while in a liquid state, poured between the outerwall of the inner mold and the inner wall of the outer one, and theinner moldY filled with a soap of a different color.

In al few moments these two compositions will become sniiciently set toallow of the withdrawal of the inner mold without the risk of the twocoalescing,so as to make the outline of the figure indistinct. This,however, should `be done while the two .masses are suiiiciently plasticto insure cohesion as one mass.

Fig. Strepresents an inner mold, in the form of letters arranged toindicate the manufactureras name. In this case each letter constitutes aseparate mold; but the method of producing the result is the same asabove explained. Where, however,molds of this character are employed,there is greater opportunity of giving variety to the appearance ofthearticle, inasmuch'as a different shade of color can be used for thecontents of each mold.

What I claim as my invention, and desire to secure by Letters Patent,isp The improvement in soap described, consisting of a bar or cake ofsoap made up of soaps of diierent colors, and arranged so as to exhibitan ineiaceable ornamental design or trade-mark intone or morecontrasting colors, the article being substantially as specified.
